Built a prop board need an idea of how to clean up the peripheral interface.

Ok so Im still working on this thing its in prototype form. Basically I need to learn KiCad and build a real board and I also have alot of testing to do with different crystal settings. I hit the prop scene after uontroller went out of buisness which is a shame becuase he had some cool stuff. Anyways I just saw a spin studio yesterday and realized in the state my board is in right now it is alot similar as far as using wing type add ons.

So there is a connection on my board for 5v and 3.3v, thats what the two screw terminals are for. Things like vga, sound, ps/2 all require voltage or at least ground connections. Now the only real convient way i figured was to run wire from the add on board to those screw jacks. That looks messy though, I didnt see a gob of wires running around the spin studio board. Does anyone know a clean way I could get power lines to add on boards? How did the spin studio system work?

See im trying to get rid of the black/red wire on the vga the green on sound..

    Have a look through the mainboard document.

    Here is what I have done with my Protoboard for prototyping use. It provides +3.3, +5 and ground as well as the I/O pins and has worked well for me. Still using the same protoboard I bought 3 or 4 years back. Perhaps you can do something similar for your modules.

    I did not understand what you really wnat to do.
    As soon as you have a professional PCB with copper on the downside and the upside there are a lot of possabilities to connect things.

    If you want to use a dot-matrix proto-PCB. a lot of isolated wires can cross each other on the downside of the PCB.
    Why don't you just route isolated wires on the downside of your PCB near to your VGA, Sound or whatever connector and solder a femaile header on the PCB with
    one more contact for ground and one more contact for 3.3V or whatever is needed.

    So where is the problem?

    best regards
